The adsorption and reactivity of citrate anions, cyanide anions, and the Au(I) and Au(III) cyanocomplexes (KAu(CN)2 and KAu(CN)4, respectively) on gold polycrystalline electrodes have been investigated by means of cyclic voltammetry and in situ FTIR spectroscopy in pH 7 sodium…

Voltammetry and FTIR–ATR techniques have been employed to investigate polyphenol films formed on platinum surfaces by electrochemical oxidation of phenol. The media used in the electropolymerization were aqueous carbonate solutions, with and without Na2S. The polymeric films created are not…

The electrodeposition of lead dioxide from lead(II) nitrate in an acid medium has
been used as a test reaction to study the effects of an ultrasound field. The different behaviours found between platinum and glassy carbon electrodes have been compared…

Doped tin dioxide electrodes have been prepared by a standard spray pyrolysis technique. The electrochemical behaviour of these electrodes has been investigated by cyclic voltammetry in sulphuric acid using the Fe2+/Fe3+ redox couple system as test reaction. Oxygen evolution has…

The aim of this paper is the characterization of a carbon felt (Le Carbone
Lorraine, RVC 4002) to be used as three-dimensional electrode. A wide
group of very different techniques were used in the physical and structural
characterization of this…

In the industrial obtention of D-a-p-hydroxyphenylglycine the separation of the amino acid is carried out by precipitation and during this process, a mother liquor is produced with a high salt content (phosphates and sulphates) and an amino acid concentration of…

The electrochemical behaviour of glycine on well-defined Pt(100) and Pt(110) electrodes has been studied in an acid medium by means of cyclic voltammetry and in situ FTIR spectroscopy. The results presented in this paper and those reported previously for the…

Antimony-doped tin dioxide electrodes supported on titanium have been used in the electrochemical treatment of aqueous solution
containing phenol. Ti/SnO2–Sb anode has high efficiency in the elimination of phenol, but its use is hindered by its short service
life. The…

A detailed study about the synthesis, characterization and properties of poly(o-methylaniline)(PoMea)/maghnite nanocomposites
has been performed. Changes in the characteristics of the nanocomposites, depending on the intercalated cation
between the clay layers before the synthesis, have been observed. Intercalated morphology has…

The mass transport rates to planar electrodes, in a series of electrochemical laboratory filter-press reactors were measured to quantify the effects of the inlet and outlet design manifolds on the fluid flow. In small reactors, entrance/exit effects are especially important…
